摘要：

The sealing ability of copal varnish has been investigated when used as an adjunct in restorative procedures, retrofilling procedures, and dontic obturation procedures. Barrier, a polyamide-type polymer cavity varnish, has been compared with copal varnishes in restorative dentistry. This investigation compared the apical sealing properties of a zinc oxide and eugenol sealer (Roth) with a polyamide varnish (Barrier). Twenty-four teeth were instrumented and divided into two groups, one obturated with gutta-percha and Roth sealer and one with gutta-percha and Barrier, using submersion in methylene blue dye to demonstrate apical leakage. Roth sealer exhibited less dye penetration than Barrier when used as an endodontic sealant (p < 0.02).
